    Abstract: A display device with a built-in optical image sensor includes a display panel, a cover substrate, and an optical image sensor. The cover substrate has light transmissivity and covers the display panel. The optical image sensor is coupled to the display panel and senses an image of a body of a user using light reflected from the body of the user in contact with the cover substrate. The display panel includes a base substrate, a pixel portion, an encapsulation film, and a touch sensing layer. The touch sensing layer includes the touch electrode portion and is disposed on the encapsulation film covering a pixel portion. A plurality of pinholes are defined in at least one layer having light absorptivity or light reflectivity of the pixel portion. The plurality of pinholes overlap the optical image sensor. Further, openings overlapping the plurality of pinholes are defined in the touch electrode portion.

    Abstract: The present disclosure provides a touch display panel or a touch display device and a gate driving circuit included in the touch display panel or the touch display device. The gate driving circuit includes a shift register group outputting scan signals during a display driving period and a dummy shift register group outputting dummy signal during a touch driving period. The gate driving circuit transmits a signal output immediately before a display driving period before a touch driving period ends, through dummy shift registers during the touch driving period such that the signal is used for outputting a first scan signal in the next display driving period. Accordingly, it is possible to prevent output reduction of a scan signal at the boundary between the touch driving period and the display driving period and prevent defect in an image due to the output reduction.
